dennisinaz,

You must have been using the non-bonded DGX, eh ?
And in the .458 Lott it was your handload, eh ?
Right, don't ever do that again.

A soft lead Lyman PH 475-grainer from a .45-70 Gov't. at 1300 fps MV is indeed a great bison penetrator,
proven to bag well by Saint Bill Bagwell.
I was enlightened late in life.
Resistance of tissue to penetration goes up exponentially with velocity.
Slow FN, soft lead, does not expand much so does not pop the drag chute either.

I shot the bison with the soft at 50 yards and he turned and ran.
Next in my magazine was the FN solid, chambered as he began his run.
He went down when hit in the rear end with that solid.

I was amazed that the soft had not exited on a broadside shot encountering no bone greater than ribs.
I was amazed that the solid exited his neck when he was hit in the ham at about 75 yards.

So I replicated the shots at 25 yards after he was dead.
Still no exit with soft on broadside chest.
FN solid sailed right through full length of body again.

I believe Sir Jerry did similar testing on his dead dinosaur, using the 480-gr DGX-Bonded and DGS.
Good results on the DGX-Bonded.
No doubt testing inspired by non-bonded version.
Any Curious George like us would do the same.

My bison was a 5-1/2 year-old bull.
Best used for burger. No worries about choice cuts there.

Speaking of bent expanding bullets,
a bent expanding bullet that does not expand is a nuisance too.
After the GSC HV .510/450-gr monometal copper at 2650 fps MV performed so well,
an insurance shot into the spine at base of neck was done post mortem,
from close range.
Gerard Shultz re-designed the 450-grainer after seeing this,
fresh from the skinning shed.
Bullet not gone to sleep at 5 yards, from a 1:10" twist ?

The hit at 50 to 75 yards broke a shoulder and heart and lungs.
The insurance shot was done into spine between shoulders, dead buffalo lying on its side, about 5 yards range:

I like Shock Hammers now.
The DGX-Bonded .458-caliber 480- gr and 500-grainers have lots of great reports
from the likes of gunner500 and Phil Shoemaker.
Those would be at 2100 to 2200 fps impacts.
Maybe I do not need to get them up to 2400 fps in a .458 WM+ handload.
But from the looks of this .375/300-gr DGX-Bonded at +2500 fps impact,

the .458 bullets could probably stand up to it too.

"First gen DGX" is not "DGX-Bonded" by Hornady,
bless their hearts, they might have finally made a decent soft for use in DGR.

DGX bonded is a very good bullet

Example just two for me, but slamming giant hip bones at 5 yards at near double rifle regulation velocity of 2148 fps the .458 cal 480gr DGX did a great job, the one put in the brisket and found in upper shoulder worked too, post mortem hip bone shot was the real test.

Hey RD, the great 500-450 3-1/4" Nitro Express, iirc you have one too, mine regulates 480gr DGS/DGX in it's 26" barrels beautifully at 65 yards at 2148 fps over H-4831.

Thank you. Yes I have the same. Due to COvid and wet weather, and now just getting out of hospital, I haven’t had a chance to try your load. But I certainly will and report my results.

With 5 shot's in the chest and none exiting, what kept it turning at all? And all five shots within 20yds? Amazing!

Ron,
As you know, I shoot a FN 485 cast .458 cast maybe 12BHN, bullet at 1750 or so. I can compare entry to exits and say likely getting some expansion on whitetail. I’ve never caught one except in a protein feed tub plastic skin and 200lbs of moist protein supplement. 20-22 inches of penetration and a nice mushroom. These tubs are more resistant than any game I’ve ever shot. They will also catch a 358 250 Hornady spt at 2600 fps again nicely mushroomed.

Not "tested" in game, but tests of bullets in tough media intended for large and/or dangerous game, I've done on several occasions. The purpose is NOT to simulate animal penetration but comparative results of several at the same time in the same media. The media is mostly dry, glossy magazines with a mix of wood, dry news print and hardcovers wedged in a strong cardboard box which itself is part of the mix. Solids will usually give complete penetration and get lost in the background. But briefly, the 500gr DGX has outperformed the 550 Woodleigh Weldcore and 450 AF by a significant amount, and the best of any .458" expanding bullets I've tried.

Good deal Rockdoc, what's that movie line?.............."it sure is a daisy" LOL!

All joking aside, i was rec'd 70gr 3031 and 3gr pufflon, didn't like the idea but loaded anyway, they shot fine and to regulation, i put 12 rounds on a shell belt and wore it around the farm doing chores and standard daily activities, the ammunition hung just like it would on Safari, well, you guessed it!

Around dark i pulled the belt and 10 out of the 12 rounds had pushed the 3gr pufflon up off the powder charge, i could shake the ammo and hear the powder was not tight against the primer, so, now here we are leveling the rifle for a shot at a Cape Buffalo, primer detonation shoots across all the powder lying in the bottom half of the huge case, has enough energy to dislodge the bullet where it sticks in the rifling, the primer fire then bounces back to ignite powder charge where upon detonation immediately hits the obstruction which is the lodged bullet in the barrel.

BOOM, rung chamber or bulged/split barrels at the very best, exploded rifle and getting smoked by a buffalo at the very worst, never again Sir.

Plus, that nice warm feeling in your hand as that big slow burning low pressure case filling charge of powder burns down the full length of the barrels. smile

Accurate, safe, case filling with all the temp stability of any powder ever made.

Dang, i missed this, Bob, is there a way i can mail you a few 500 grain 458 cal partitions for testing, i think you'll find these to be the world champ penetrating soft point bullet, PM me an address if it's doable.
